Verbena plant named ‘KLEVP15618’

ABSTRACT

A new  Verbena  plant particularly distinguished by violet-blue flowers, a semi-upright plant habit, and good tolerance to powdery mildew, is disclosed.

Genus and species: Verbena sp.

Variety denomination: ‘KLEVP15618’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct variety of Verbena,botanically known as Verbena sp., and hereinafter referred to by thevariety name ‘KLEVP15618’. ‘KLEVP15618’ originated from across-pollination conducted in September 2011 in Cobbitty, New SouthWales, Australia between the proprietary female Verbena variety ‘VC1293’(unpatented), and the proprietary male Verbena variety ‘VC1215’(unpatented).

The seeds from the cross were sown and plants were grown for evaluation,where an individual plant designated ‘KLEVP15618’ was selected from thegroup of plants in Cobbitty, New South Wales, Australia in August 2012.

In October 2012, ‘KLEVP15618’ was first vegetatively propagated byvegetative stem cuttings in Cobbitty, New South Wales, Australia.‘KLEVP15618’ was found to reproduce true to type in successivegenerations of asexual propagation via vegetative stem cuttings.

SUMMARY

The following are the most outstanding and distinguishingcharacteristics of this new variety when grown under normalhorticultural practices in Cobbitty, New South Wales, Australia.

-   -   1. Violet-blue flowers;    -   2. A semi-upright plant habit; and    -   3. Good tolerance to powdery mildew.

DESCRIPTION OF THE PHOTOGRAPH

This new Verbena plant is illustrated by the accompanying photographwhich shows the plant's overall plant habit including form, foliage, andflowers. The photograph is of a thirteen- week-old plant grown in agreenhouse in Stuttgart, Germany in May 2014.

The colors shown are as true as can be reasonably obtained byconventional photographic procedures.

DESCRIPTION OF THE NEW VARIETY

The following detailed descriptions set forth the distinctivecharacteristics of ‘KLEVP15618’. The data which define thesecharacteristics were collected from asexual reproductions carried out inCobbitty, New South Wales, Australia. Data was collected onthree-month-old plants grown in a greenhouse in Cobbitty, New SouthWales, Australia in June 2015 in Cobbitty, New South Wales, Australia.Color references are to The R.H.S. Colour Chart of The RoyalHorticultural Society of London (R.H.S.) 2007.
